The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

In Nov. 1864, R.A.S. council instructed secretary Charles Pritchard to write to JH regarding tables by late [W. L.] Newman of York, but JW finds no evidence that Pritchard complied. Cannot find Newman's tables. Pritchard may have taken them.
Has sent JH a copy of his new book [The Sun].
Raises objections to JH's theory of the solar corona. Discusses possible existence of extensive meteoric dust in the solar system. Requests permission to dedicate a book on sidereal astronomy to JH. Asks JH whether his father in later years always used a front focus for his large telescopes and whether he saw the supposed four additional Uranian satellites with his 40-foot reflector.
Discusses JH's response to his comments on JH's theory of the solar corona. Discusses great difficulty of writing his planned book on sidereal astronomy.
Reports on recent solar eclipse photographs of the solar corona which jeopardize JH's meteoric theory of the corona's origin. Concludes the corona must be 'after all a phenomenon of eruption!!'
Suggests that meteors come sometimes from the sun, more typically from other stars.
Outlines the recent work in terrestrial magnetism by H. T. R. Petersen and himself. Comments on their results.
Thanks JH for assistance in settling matters with the B.A.A.S.; comments about travel plans and magnetic observations.
Regrets that his bad handwriting caused JH to misread some of his remarks. Will try to produce a clearer exposition of his results. Comments on his expositions.
